WATER-HEATER.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed September 15, 1915. Serial No. 50,806.

T 0 all whom it may concern.

Be it known that I, JOSEPH B. MORAN, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Water-Heaters, of which the following is a specification.

This invention relates to a water heater.

One of the objects of the present invention is to provide a simple, substantial cheaply manufactured water heater of the instantaneous heater type, which is particularly constructed to produce a large heating area together with means for insurlng a rapid and forced circulation of water within the heater in one direction.

Another object of the invention is to provide means which will permit collection of precipitates, such as sediment and the like without clogging the heating surfaces or in any way interfering with the circulation.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings in which Figure 1 is central, vertical section of the heater. Fig. 2 is a plan section on line 2 2, Fig. 1.

Referring to the drawings in detail it will be seen, that the heater comprises a casing of circular shape, consisting of two cone-shaped disks 2 and 3, which may be secured together at the periphery by welding, brazing, screws or any other suitable means. The disks are preferably flattened as much as possible, to produce a shallow chamber interior thereof, of considerable area.

Suitably secured either to the upper or lower disk, is a cone shaped baffle plate 4; this is mounted in a position with relation to the lower disk 3, so as to produce a narrow, annular passage 5, through which the water must pass before it can enter the main chamber 6, or escape through the discharge opening 7. The baffle plate is of smaller diameter than the interior periphery of the chamber and as it is spaced from the lower disk 3, an annular unrestricted discharge passage will be formed, as at 8 which communicates with chamber 6. In the present instance, the baflie plate is shown as provided with a plurality of radially disposed foot members 9; these being provided for the purpose of securing the baflie plate to one or the other of the bafiie plate et, is of The heater as a whole, may be placed W directly above a gas burner or any other form of burner, not necessarily here shown, and when thus.;pos1t1oned, it can readlly be seen that the thin film of water will be instantly heated, thereby causing a rapid and forced circulation in the direction indicated, in Figrl, may be connected together and surrounded by a casing and connected with a hot water tank or the pipe line service of a building. The heater may also be installed in flues or attached to other forms of heaters to utilize waste heat and act as boosters to insure a rapid; circulation. The provision great importance, as it first of all permits a thin film of water to be exposed to the heating surface. It furthermore, insures rapid circulation and also acts as a mud drum to collect any mud or sediment contained in the water. The sediment collecting on the inside of the baffle plate which in this instance forms a false bottom for chamber 6, does not interfere with circulation of the water through the heat unit, nor does it affect or clog the heating surfaces in any manner, as the baflie plate is spaced from and supported above the main heating surface. The shape of the heater, furthermore presents a great area and while the surface 3 is more directly exposed to heat than the surface of plate 2, it will be seen that both surfaces or plates will transmit heat to the water. The provision of the baffle plate makes it impossible for water to pass directly through the heater, as is common in many forms of heaters.

The materials and finish of the several parts of the device may be such as the judgment and experience of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to Within the scope of the appended claims, and that I do Several units, such as indicated' not Wish to limit myself to the specific design and construction here shown.

Having thus described my invention, What I claim and desire to secure by Letters Patent is 1. In a Water heater, a chamber, having a top and bottom, an inlet pipe at the center of the chamber bottom, an outlet pipe at the center of the chamber top, and a cone shaped baffle plate between the top and bottom extending over the inlet pipe, said bafiie plate having its concave side facing the outlet whereby said concave side will form a mud collecting pocket.

2. In a Water heater, a chamber formed of a pair of cone-shaped plates secured together, an inlet and an outlet at the respective apices of the plates, and a cone-shaped baffle plate having its apex presented to the inlet and disposed to form a relatively shallow passage in conjunction With the adjacent chamber plate, the concave side of the baffle plate being presented to the outlet to form a mud collecting pocket.

3. In a Water heater, a chamber having a top and bottom, an inlet pipe at the center of the chamber bottom, an outlet pipe at the center of the chamber top, and a combined baflle and mud collector between the inlet and outlet arranged to trap sediment carried by the Water in the passage of the latter from the inlet over the bafiie to the outlet and to spread the Water in a comparatively thin film.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
